WARNING
SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not
properly installed, used, and maintained. Misuse of this equipment and other
unsafe practices can be hazardous. The operator, supervisor, and helper must read
and understand the following safety warnings and instructions before installing
or using any welding or cutting equipment, and be aware of the dangers of the
welding or cutting process. Training and proper supervision are important for a safe
work place. Keep these instructions for future use. Additional recommended safety
and operating information is referenced in each section.
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH
Install and maintain equipment in accordance with the National Electrical Code
(NFPA 70) and local codes. Do not service or repair equipment with power on.
Do not operate equipment with protective insulators or covers removed. Service
or repair to equipment must be done by qualified and/or trained personnel only.
Do not contact electrically live parts. Always wear dry welding gloves that
are in good condition. Aluminized, protective clothing can become part of the electrical path.
Keep oxygen cylinders, chains, wires, ropes, cranes, and hoists away from any part of the
electrical path. All ground connections must be checked periodically to determine if they are
mechanically strong, and electrically adequate for the required current. When engaged in AC
welding/cutting under wet conditions or where perspiration is a factor, the use of automatic
controls for reducing the no load voltage is recommended to reduce shock hazards. Accidental
contact must be prevented when using open circuit voltage exceeding 80 volts AC, or 100
volts DC by adequate insulation or other means. When welding is to be suspended for any
length of time, such as during lunch or overnight, all electrode holders and electrodes should
be removed from the electrode holder and the power supply should be turned off to prevent
accidental contact. Keep MIG Guns, electrode holders, TIG torches, Plasma torches, and
electrodes away from moisture and water.
MESURES DE SÉCURITÉ
AVERTISSEMENT
DES BLESSURES GRAVES OU MORTELLES peuvent résulter d’une installation,
d’un usage ou d’un entretien inadéquat de l’équipement de soudage et de décou-
page. Une mauvaise utilisation de cet équipement et d’autres pratiques risquées
peuvent être dangereuses. L’opérateur, le superviseur et l’aide doivent lire et com-
prendre les avertissements et les instructions de sécurité suivantes avant d’installer
ou d’utiliser tout équipement de soudage ou de découpage et être conscients des
dangers inhérents aux processus de soudage et de découpage. Une formation et
une supervision adaptées sont importantes pour assurer un lieu de travail sûr.
Gardez ces instructions pour une utilisation future. Chaque section comporte des
informations supplémentaires de sécurité et de fonctionnement.
UN CHOC ÉLECTRIQUE PEUT CAUSER DES BLESSURES OU LA MORT
L’installation et l’entretien de l’équipement doivent être conformes au Code national
de l’électricité NFPA 70 et aux codes locaux. N’effectuez pas l’entretien ou la
réparation d’équipement en marche. N’opérez pas l’équipement sans isolateurs ou
caches de protection. L’entretien ou la réparation de l’équipement doivent être
effectués uniquement par un technicien qualifié ou par du personnel formé.
Ne touchez pas aux pièces électriques chargées. Portez toujours des gants de soudage au sec
et en bon état. Les vêtements de protection aluminisés peuvent devenir une partie du chemin
électrique. Éloignez les bouteilles d’oxygène, les chaînes, les câbles métalliques, les appareils
de levage, les treuils et les élévateurs de toute partie du circuit électrique. Toutes les liaisons de
terre doivent être vérifiées périodiquement pour déterminer si elles sont solides et appropriées au
courant demandé. En cas de soudage ou de découpage en courant alternatif dans des conditions
d’humidité ou de chaleur où l’opérateur risque de transpirer, il est recommandé d’utiliser des
contrôles automatiques pour réduire la tension à vide et ainsi diminuer les risques de choc
électrique. Lorsque le procédé de soudage et de découpage exige des valeurs de tension en
circuit ouvert dans des machines à courant alternatif supérieur à 80 volts ou dans des machines
à courant continu supérieur à 100 volts, il faut prendre des mesures pour empêcher un contact
accidentel en prévoyant une isolation adéquate ou d autres moyens. Lorsqu’il faut interrompre les

SAFETY AND OPERATING INSTRUCTIONS
89200016
SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH
Ventilation must be adequate to remove smoke, fumes, and gases during
operation to protect operators and others in the area. Vapors of chlorinated
solvents can form the toxic gas "Phosgene" when exposed to ultraviolet
radiation from an electric arc. All solvents, degreasers, and potential sources
of these vapors must be removed from the operating area. Use air-supplied
respirators if ventilation is not adequate to remove all fumes and gases. Oxygen supports, and
vigorously accelerates fire and should never be used for ventilation.
ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN
Welding and cutting processes produce extreme localized heat and strong
ultraviolet rays. Never attempt to weld/cut without a federally compliant
welding helmet with the proper lens. A number 12 to 14 shade filter lens
provides the best protection against arc radiation. When in a confined area,
prevent the reflected arc rays from entering around the helmet. Approved
shielding curtains and appropriate goggles should be used to provide protection to others in
the surrounding area. Skin should be protected from arc rays, heat, and molten metal. Always
wear protective gloves and clothing. All pockets should be closed and cuffs sewn shut. Leather
aprons, sleeves, leggings, etc. should be worn for out-of-position welding and cutting, or for
heavy operations using large electrodes. Hightop work shoes provide adequate protection from
foot burns. For added protection, use leather spats. Flammable hair preparations should not be
used when welding/cutting. Wear ear plugs to protect ears from sparks. Where work permits,
the operator should be enclosed in an individual booth painted with a low reflective material
such as zinc oxide.
WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS
Combustibles reached by the arc, flame, flying sparks, hot slag, and heated
materials can cause fire and explosions. Remove combustibles from the
work area and/or provide a fire watch. Avoid oily or greasy clothing as a
spark may ignite them. Have a fire extinguisher nearby, and know how to use
it. If welding/cutting is to be done on a metal wall, partition, ceiling, or roof,
precautions must be taken to prevent ignition of nearby combustibles on the
other side. Do not weld/cut containers that have held combustibles. All hollow spaces, cavities,
and containers should be vented prior to welding/cutting to permit the escape of air or gases.
Purging with inert gas is recommended. Never use oxygen in a welding torch. Use only inert
gases or inert gas mixes as required by the process. Use of combustible compressed gases
can cause explosions resulting in personal injury or death. Arcing against any compressed gas
cylinder can cause cylinder damage or explosion.
NOISE CAN DAMAGE HEARING
Noise from the air carbon-arc process can damage your hearing. Wear
protective hearing devices to ensure protection when noise levels exceed OHSA
standards. Adequate hearing protection devices must be worn by operators and
surrounding personnel to ensure personal protection against noise.

SECTION 2: INTRODUCTION
activités de soudage pendant un certain temps, à l’heure du repas ou la nuit, par exemple, il faut
enlever toutes les électrodes du porte-électrode et mettre hors tension l’alimentation pour éviter
tout contact accidentel. Gardez les pistolets MIG, les porte-électrodes, les torches TIG, les torches
à plasma et les électrodes loin de l’humidité et de l’eau.
LA FUMÉE, LES ÉMANATIONS ET LES GAZ PEUVENT ÊTRE DANGEREUX POUR VOTRE
SANTÉ
La ventilation doit être suffisante pour enlever la fumée, les émanations et les
gaz pendant le fonctionnement de la torche afin protéger les opérateurs et les
autres personnes présentes dans la zone. Les vapeurs de solvants chlorés
peuvent former un gaz toxique appelé « Phosgène » si elles sont exposées au
rayonnement ultraviolet d un arc électrique. Il faut enlever de la zone de travail
tous les solvants, décapants et sources potentielles de ces vapeurs. Servez-vous d’appareils
respiratoires à adduction d’air si la ventilation n’est pas suffisante pour enlever toutes les
émanations et gaz. L’oxygène alimente les incendies et en accélère la propagation il ne faut
jamais l’utiliser à des fins de ventilation.
L LES RAYONS DE L’ARC, LES SCORIES ET LES ÉTINCELLES CHAUDS PEUVENT
BLESSER LES YEUX ET BRÛLER LA PEAU
Les procédés de soudage et de découpage produisent une chaleur extrême
localisée et de puissants rayons ultraviolets. N’essayez jamais de souder ou de
couper sans casque soudage conforme aux normes du gouvernement fédéral et
muni d’une lentille appropriée. Des lentilles à filtre de numéro 12 à 14 fournissent
la meilleure protection contre le rayonnement de l’arc. Dans un endroit confiné, il faut éviter que
les rayons reflétés de l’arc n’entrent autour du casque. Il faut utiliser des rideaux de protection
approuvés et des lunettes de protection appropriées pour protéger les autres personnes se
trouvant aux abords. Il faut aussi protéger la peau nue des rayons de l’arc, de la chaleur et du
métal fondu. Portez toujours des gants et des vêtements de protection. Toutes les poches doivent
être fermées et les manchettes, cousues. Il faut porter un tablier, des manches, des guêtres, etc.
en cuir pour effectuer de soudage ou de découpage et dans le cas des activités intensives
nécessitant de grandes électrodes. Les chaussures de sécurité montantes fournissent une
protection suffisante contre les brûlures aux pieds. Pour obtenir une plus grande protection,
portez des guêtres en cuir. Il ne faut pas utiliser de produits capillaires inflammables avant
d’effectuer des activités de soudage ou de découpage. Portez des bouchons d’oreilles pour vous
protéger les oreilles des étincelles. Lorsqu’il est possible de le faire dans la zone de travail,
l’opérateur doit s’isoler dans une cabine individuelle recouverte d’un revêtement à faible
réflectivité, comme l’oxyde de zinc.
LES ÉTINCELLES DE SOUDAGE PEUVENT CAUSER DES INCENDIES ET DES
EXPLOSIONS
Les combustibles atteints par l’arc, les flammes, les vols d’étincelles, les scories
chaudes et les matériaux chauffés peuvent causer des incendies et des
explosions. Enlevez les combustibles de la zone de travail ou mettez en place du
personnel de surveillance. Évitez les vêtements huileux ou graisseux, car une
étincelle peut y mettre le feu. Ayez un extincteur à proximité et sachez comment
l’utiliser. Si l’activité de soudage ou de découpage doit être fait contre un mur, une cloison, un
plafond ou un toit, il faut prendre des précautions pour d’enflammer des combustibles qui se
trouveraient à proximité, de l’autre côté. Ne soudez pas et ne coupez pas de conteneurs ayant
contenu des combustibles. Il faut aérer tous les espaces creux, les cavités et les conteneurs avant
de les soumettre au soudage ou au découpage afin d’évacuer tout l’air ou le gaz qui peut s’y
trouver. Il est recommandé d’effectuer une purge avec du gaz inerte. N’utilisez jamais d’oxygène
dans une tête de soudage. N’utilisez que des gaz inertes ou des mélanges de gaz inertes,
conformément aux exigences du procédé. L’utilisation de gaz combustibles comprimés peut
causer des explosions entraînant des blessures ou la mort. Le fait d’utiliser l’arc sur une bouteille
de gaz comprimé peut endommager la bouteille ou causer une explosion.
LE BRUIT PEUT ENDOMMAGER L’OUÏE
Le bruit du procédé de l’arc avec électrode en carbone et jet d’air peut
endommager l’ouïe. Portez un dispositif de protection de l’ouïe pour vous
protéger lorsque le niveau de bruit dépasse les normes de l’OSHA. Les
opérateurs et le personnel aux abords doivent porter un dispositif de protection de
l’ouïe approprié pour les protéger efficacement contre le bruit.

1. Disassemble the rear case to expose the rear connector assembly and pull the assembly away from the rear case.
2. Cut the Cablehoz to remove the damaged area.
3. Use replacement connector assembly:
250 Amp - Part No. MS172-RK (Stock No. 2060-2134)
350 Amp - Part No. MS174-RK (Stock No. 2060-2135)
4. Measure back 2-1/2" (63.5mm) from the end of the Cablehoz and cut away the outer jacket of the cable, being careful not to cut the
copper strands and or lead wires.
5. Pull the copper strands and lead wires away from the inner
core tube that’s exposed and cut away leaving approximately
¼" (6.35mm) past the end of the end of the Cablehoz.
6. Cut the copper strands to a length of ¾" (19.05mm) while
leaving the wire leads intact.
7. Thread the pressure nut onto the replacement rear connector until it bottoms out and then slide the sleeve over the connector. Note:
Make sure that the end with the bevel on the inside diameter goes on rst allowing the opposite end with a ¾" (19.05mm) to be
facing the Cablehoz when assembled.
8. Insert the replacement connector into the inner core tube
of the Cablehoz. It’s recommended to use a small amount of
lubricant to help the connector to slide into the tube. The core
tube should bottom out against the shoulder, approximately
15/16" (23.8mm) onto the connector.
9. Push the copper strands underneath the sleeve. It’s recommended that a 1/8" glass lament tape be wrapped around the exposed
copper to keep the copper strands together.
10. Begin to turn the pressure nut counter-clockwise which will
force the copper strands & sleeve against the machined taper
on the connector.
11. Torque the pressure nut to 250 inch pounds (+/-50 inch pounds).
12. Position the metal Band-it strap that came with the repair kit 1/4" (6.4mm) from the front edge of the outer jacket on the
Cablehoz. You will need to purchase the tool to secure the clamp down against the Cablehoz, Part No. 136TOOL (Stock No.
2060-2691) and follow the manufacturer's procedure included with this tool.
13. Connect lead wires accordingly.
14. Reassemble the rear case.
B. Front-End Repair

SECTION 7: TROUBLESHOOTING
Contact tips and nozzles should be cleaned frequently. Spatter buildup may cause bridging between nozzle and tip. This could cause electrical shorting between the nozzle and work piece as
well as poor or improper gas flow. Regularly inspect the conductor tube, handle, cable, and other parts of the MIG Gun for abrasion, cuts, or undue wear. Replace or repair any parts found
deficient. Refer to www.Tweco.com for MIG Gun troubleshooting chart(s).
